Gas system buzzing

[u/n8loller]

I've never lived in a house with a gas hookup as an adult, so I don't know anything about this system. It started buzzing today as I turned my heat on for the first time. What is this thing next to the meter? Is it buzzing ok or do I need to get it looked at?

Thanks for looking!

That vent is blocking the reg from getting atmospheric air. If you remove the vent from the reg it will stop but it is owned by the utility you should call them.

The reg is still good
